An ion has 19 protons and 18 electrons. What is the charge of this ion?
A
+2
B
0
C
+1
D
-1
Verified step by step guidance1
Identify the number of protons and electrons in the ion. Here, the ion has 19 protons and 18 electrons.
Recall that the charge of an ion is determined by the difference between the number of protons (positive charges) and electrons (negative charges).
Calculate the net charge using the formula: $\text{Charge} = \text{Number of protons} - \text{Number of electrons}$.
Substitute the given values: $\text{Charge} = 19 - 18$.
Interpret the result: since there is one more proton than electrons, the ion has a charge of $+1$.
